Conor McGregor just sent a loud and clear message to Floyd Mayweather.

Mayweather had extended an invite to McGregor, which would allow the UFC fighter to use all of the equipment at the Mayweather Boxing Club ahead of his comeback bout at UFC 229.

But rather than accept the invite, McGregor took to Twitter stating “F— the Mayweathers” – the controversial line he immortalised during the whirlwind press tour ahead of his own fight with Mayweather last year.

But McGregor responded to Mayweather in the most “Notorious” way possible. He looked at the invite and metaphorically ripped it up without hesitation, reigniting his former rivalry with Mayweather in a massively public setting – Twitter.

McGregor even reiterated the immortal and offensive “f— the Mayweathers” line that he used throughout the whirlwind pre-fight press tour in 2017.

“F— the Mayweathers except Senior and Roger,” he said. “There is no peace here, kid. Step up, or step down.”

Fuck the Mayweathers, except Senior and Roger. There is no peace here kid. Step up or step down.
